What I would do is subtract 6x from both sides and subtract 48 from both sides you get 2x = 24 divide by two and x = 12

Alaina has $72 and earns $6 each day, Joel has $48 and earns $8 each day. In How many days will joel have as much money as Alaina?
A=72($)+6($/day)*D(day)
J=48($)+8($/day)*D(day)
A=J (Alaina and Joel must have the same ammount of money)
(72+6D)($) = (48+8D)*($) (note that system units is $-money and simplifies at the end)
24=2D
D=12
